Abstract

Die Erfindung betrifft eine Fehlererkennungseinrichtung (23) für Brennkraftmaschinen und ein Verfahren zum Betreiben einer Brennkraftmaschine (1) mit zumindest zwei Abgassträngen (21,22), jeweils einer Lambda-Sonde (27,28) in einem Abgasstrang, einer gemeinsamen Meßvorrichtung (3) zur Erfassung der zugeführten Luft und einer gemeinsamen Steuereinrichtung (29) zur Zumessung von Kraftstoff. Um eine Brennkraftmaschine mit einer verbesserten Fehlererkennung zu schaffen wird vorgeschlagen, Lambdasonden einzusetzen, die ein stetiges Signal für den Lambdawert des Abgases erzeugen. Die Fehlererkennungseinrichtung erkennt dann einen Fehler, wenn die von den Lambdasonden gelieferten Signale voneinander abweichen.

The invention relates to a fault detection device (23) for internal combustion engines and a method for operating an internal combustion engine (1) with at least two exhaust gas lines (21, 22), each with a lambda probe (27, 28) in an exhaust line, and a common measuring device (3). for detecting the supplied air and a common control device (29) for metering fuel. In order to create an internal combustion engine with improved error detection, it is proposed to use lambda sensors that generate a steady signal for the lambda value of the exhaust gas. The error detection device then detects an error if the signals supplied by the lambda sensors differ from one another.
